Cardiac index is calculated by measuring cardiac output
using one of a number of possible methods and dividing the results by the individual's body surface area, a fairly complex process.
Hospitals are the main end-user of the non-invasive and minimally-invasive cardiac output
The non-invasive cardiac output
measuring device NICOM (Cheetah Medical, Portland, OR) was used in the experiment to measure cardiac output
Estimates of the true accuracy and precision of PiCCO compared with other cardiac output
devices are variable and currently unreliable.
Venous blood relapse is reduced during every birth pang in women in childbirth with RHD in supine posture and this makes it difficult to ensure the necessary increase of cardiac output
, and, accordingly, adequate blood supply of uterus and oxygenation of foetus.
We haven't yet tested cardiac output
with MRI during exercise prepregnancy, but if women at risk are tested before or during pregnancy and cardiac output
is found to be lacking, this might be an indication to treat them more intensively, maybe with diuretics or other medications.
2] content completes the Fick equation, permitting an estimation of cardiac output
The relationship between stretched myocardial muscle fibers and decreased cardiac output
is also noted in Laplace's Theorem (Hudak & Gallo, 1973, p.
Statistics: Analysis of variance for repeated measurements was used to compare the effect of head-up tilt on heart rate, stroke volume, total peripheral resistance and cardiac output
(stroke volume, total peripheral resistance and cardiac output
are given as change percentages from supine values) between the groups.
The cardiac output
is calculated from information such as pulse rate and pulsatility from the arterial pressure waveform after correction for body height and weight, age and gender.
In contrast to 18 normotensive men and women who were long-term practitioners of transcendental meditation, the 14 normotensive control subjects who were observed while resting with eyes-closed showed increased total peripheral resistance and decreased cardiac output
and stroke volume, the researchers reported.
